| They have black bristles on the central section of the chest and two fine dark, longitudinal lines are visible there. The common yellow dung fly has greyish-brown transparent wings with red to yellow edges at the front. The abdomen of the females is greyish-brown with black hair, while the abdomen of the male is light yellow in colour.

| The females lay their eggs in dung heaps and the larvae develop there. The larvae reach body lengths of up to 10 mm and prey on other insects’ larvae (mostly Diptera). | | |

| ...ntire abdomen is wedge-shaped and almost black in colour, with reddish-yellow markings on the second segment which do not extend onto neighbouring segments (as is the case in other Eristalis species). These markings have yellowish-brown hair. In the females the markings on the 2nd abdominal segment are hard to make out because they are very indistinct. The brownish, feathery bristles on the antennae are a striking feature of the drone fly. The compound eyes are unusually large and touch in the males. T... | | |

| Frit flies | | ...ies are mainly active in autumn and can often be found in large numbers on lawns. Frit flies also often enter human dwellings, en masse where they are perceived as an annoyance.
Frit flies feed on sugary liquids such as nectar or honeydew. The females lay their eggs on the leaves of plants (mostly grasses), mushrooms, flowers or fruits. The hatched larvae then live inside the plants on which they feed. Some species of larvae prey on insects, other species feed on dead plant parts. | | |
|
| Yellow swarming flies are encountered mainly in grasslands. When they are on the hunt for habitats to overwinter, they sometimes appear in swarms of millions (mostly females) in residencial and other buildings. Each year they return to the same buildings. The reasons for this are uncertain. The adult flies overwinter without food. | | |
|
| The females lay their eggs in spring, on grasses where their larvae then develop . The larvae of yellow swarming flies feed rapaciously on some species of Pseudococcidae and on aphids. They pupate in the soil. Some of the pupae overwinter there. The life expe... | | |

| Green long-legged fly | | ...tera, the family long-legged flies (Dolichopodidae) and to the genus Poecilobothrus. This species is commonly found throughout the world especially in Europe. The green long-legged fly reaches body lengths of 2-8 mm. The males are larger than the females. The bodies of the flies are brightly coloured and have a metallic sheen. Their large compound eyes have a red and greenish shimmer. | | |
|
| The antennae of the males and females differ in shape. Their mouth parts are designed for preying on small insects. The thorax of the green long-legged fly is shiny, gold-green and hairy. | | |
|
| The sage leafhopper reproduces several times in the course of a year. The females lay their eggs on the food plants of the nymphs. The last generation of the year overwinter as eggs. Sage leafhoppers can be observed from May to late autumn. The adults are shy and fly away rapidly when disturbed. Among the natural enemies of the n... | | |

| Ants can form permanent nests or be nomadic. They are highly organized and have a social stratification system (caste system), with each insect performing a particular task. Several million ants can live in a colony. Most of these are infertile females and are workers or soldiers with duties both outside and inside the nest.
Only the queen ant can produce eggs. The males - like the young queens – have wings, and their only task is to fertilize the eggs. The workers and soldiers are much smal... | | |
